Application filed August 5, 1922. Serial No. 579,888.

T all whom may concern:

Be it known that I, EDWARD B. Nowo- SIELSKI, a citizen of the United States, re siding at Bloomfield, in the county of Essex,

State of New Jersey, have invented certain new and useful improvements in Electric- Generatonoperating Means, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

This invention relates to means for operating an electric generator, particularly of the magneto type that furnishes sparkiIlg current to the cylinders of an internal combustion engine. In many cases it has been found highly desirable to install a high tension magneto on such engines, but in many cases such installations have been found to be difficult on account of lack of space from the equipment already installed oh the engine or chassis carrying the engine.

My invention is particularly adapted for use in connection with an engine of the Ford type. Many electric generator installations have heretofore been proposed for this style of engine, some of which schemes are shown and described in various patents, but all the schemes with which I am familiar are open to some objections. One, and not the least important, is the matter of initial cost, as well as cost of installation.

It is the principal object of my inven= tion to provide means for attaching an igni tion generator to such an engine and driving the same therefrom, which means will be simple and cheap in its first cost and extremely easy to install.

Other objects will be apparent after a study of this specification and annexed drawings, in which:

Figure 1 shows a longitudinal view of the engine with the electric generator mounted thereon.

Figure 2 is an end view of Fig. 1, but with certain of the parts broken away.

Figure 3 is a view of the mounting bracket used to carry the generator.

.Figure 1 is a detailed view of one of the parts shown in Fig. 2.

Figure 5 is a top view of Fig. 4.

Figure 6 is a somewhat enlarged view of the driving means carried on the cam shaft of the engine.

Figure 7 is a side elevation of Figure 6, while Figure 8 is a view of the electric generator and the member shown in Fig. l in an assembled position ready to go on the bracket.

Referring now to the details wherein like members refer to corresponding parts in the various views, 1 illustrates generally the engine complete, having a cooling fan 2, the lower portion of which is broken away in 2. The bracket has a pair of lugs 4 and 5 with attachment points 6 and adapted to receive the engine bolts 8 and 9 in the side of the crankcase. The upper face of the bracket is flat for the reception. of the generator frame, which is mounted thereon and held thereto by a strap 10, which terminates in holding down bolts 11 and 12, that pass through notches 13 and 14 respectively in the face of the bracket 3. A slot 15 passes across the face of the bracket 3 substantially at right angles to the line of the generator shaft. Positioned within the slot 15 is a brace 16 having one end slotted at 17 to receive an engine bolt 18. As illustrated in the drawings, engine bolt 18 is used also to hold the fan bracket. The opposite end of the brace 16 is slotted at 19 to receive locking bolt 20. Pins 21 are fastened to the brace 16 and extend upw into base holes in the bottom of the electric generator as shown in Fig. 8.

The generator shaft carries a sprocket wheel 22 suitably fastened thereto. Fast-- ened to the end of the cam gine is a flange member 23. Positioned on the flange member 23 is a driving sprocket wheel 24-, slots 25 being formed therein to receive set screws 26, which are screwed into the flange member 23 and have means for gripping the outer face of the sprocket wheel 2%. It will thus be seen that the sprocket wheel be adjusted angularly with reference to the cam shaft of the engine for a purpose which shall be hereinafter pointed out.

Passing over the two sprocket wheels 22 and 2a is a link chain 27. A casing 28 en closes the two sprocket wheels and chain and is held in position by a brace 29 passing under the head of the bolt 18 and another brace 30 held by bolt 3]. engaging a threaded shaft of the enallel to the hole 37 in the side of the bracket 8. It will thus be seen that when it is necessary to take up any stretch in the chain that the strap 16 is loosened by means of the nut on the holding down bolt 11 and loosening the clamping bolt 20 as iv-ell as the nut on the bolt 18. The electric generator is then mo red or po sitioned by pushing on the brace 16, which of itself is positioned in the slot 15, so that the generator is moved in a manner that keeps its operating shaft substantially parcam shaft of the engine. VJhen the proper position has been obtained, the above mentioned bolts are then tightened up.

In timing the generator, the set screws 26 are loosened and by a slight pull on the chain of the sprocket, both of the sprockets are moved relative to the cam shaft, therel y shifting the position of the rotating member of the electric generator with respect to the cam shaft. WVhen the proper position has been obtained, the set screws 26 are tightened in position. The guard casing 28 is cut away large enough so as to leave the set screws 26 exposed for the purpose of making the above mentioned adjustment.

An auxiliary pair of braces 32 and 33 are attached to the engine for the purpose of carrying an ignition control rod 34, when an ignition generator is used having an advance lever. On installations of this nature, a fixed spark generator is sometimes used, in which case braces 32 and 38 and rod 34: with lever 35 connecting to the timer lever 36 are not required.

This method of driving is such that it can be installed without taking off the radiator from the engine, thereby saving considerable time and work, and does not interfere with the installation of the starting motor or the lighting generator.

\Vhile I have shown the clamping bolt 20 to cooperate with the slot to hold the outer end of the brace 16 to the bracket 3, this might be omitted as the brace 16 is positioned in the slot 15 beneath the generator and cannot get out of position on account of the engagement of the pins with the holes of the generator that is securely fastened to the bracket.

Other changes and. alterations may be made in the details without departing from the spirit of my invention or the scope of the appended claims.
